The effects of the inhibitors trimethylacetyl phosphate and cAMP have been determined in reactions catalyzed by D-glyceraldehyde-3-phosphate dehydrogenase. These inhibitors must influence the oxidation of aldehydes through substrate dependent cooperative conformational changes. Both trimethylacetyl phosphate and cAMP give sigmoidal 1/V
